7x+y^3+7x^3+6x-3y^3-2x^3+3x

musickatia [10]

Answer:

5x^3 + 16x - 2y^3

Step-by-step explanation:

7x + y^3 + 7x^3 + 6x - 3y^3 - 2x^3 + 3x

group like terms

= 7x^3 - 2x^3 + 7x + 6x + 3x + y^3 - 3y^3

add similar items

= 5x^3 + 7x + 6x + 3x + y^3 - 3y^3

add similar items

= 5x^3 + 16x + y^3 - 3y^3

add similar items

= 5x^3 + 16x - 2y^3

How to do this problem??

We know that the sum of the inner angles of any triangle is 180º

72º + (7x + 3)º + (3x + 5)º = 180º
72º + 7xº + 3º + 3xº + 5º = 180
7xº + 3xº = 180º - 72º - 3º - 5º
10xº = 100º
$x^0 = \frac{100^0}{10^0}$
$x^0 = 10\to\:\boxed{\boxed{x = 10^0}}\end{array}}\qquad\quad\checkmark$

The sum of the external angle (9y + 1)º with inner angle (3x + 5) = 180 °, <span>Replace the measure of "x" found:
</span>
(9y + 1)º + (3x + 5)º = 180º
9yº + 1º + 3xº + 5º = 180º
9yº + 1º + 3.(10)º + 5º = 180º
9yº + 1º + 30º + 5º = 180º
9yº = 180º - 1º - 30º - 5º
9yº = 144º
$y^0 = \frac{144^0}{9^0}$
$y^0 = 16\to\:\boxed{\boxed{y = 16^0}}\end{array}}\qquad\quad\checkmark$

Answer:
<span>The measures of "x" and "y" are respectively: 10º and 16º</span>
